84857-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84857-13-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84857-13:
(7*8)+(6*4)+(5*8)+(4*5)+(3*7)+(2*1)+(1*3)=166
166 % 10 = 6
So 84857-13-6 is a valid CAS Registry Number.

Iron-Catalyzed Alkyne-Based Multicomponent Synthesis of Pyrimidines under Air

Chakraborty, Gargi,Guin, Amit Kumar,Mondal, Rakesh,Paul, Nanda D.,Sarkar, Susmita

, p. 13186 - 13197 (2021/10/01)

An iron-catalyzed sustainable, economically affordable, and eco-friendly synthetic protocol for the construction of various trisubstituted pyrimidines is described. A wide range of trisubstituted pyrimidines were prepared using a well-defined, easy to prepare, bench-stable, and phosphine-free iron catalyst featuring a redox-noninnocent tridentate arylazo pincer under comparatively mild aerobic conditions via dehydrogenative functionalization of alcohols with alkynes and amidines.

Iron Catalyzed Synthesis of Pyrimidines Under Air

Mondal, Rakesh,Sinha, Suman,Das, Siuli,Chakraborty, Gargi,Paul, Nanda D.

supporting information, p. 594 - 600 (2019/12/15)

Herein we report an iron-catalyzed multicomponent dehydrogenative functionalization of alcohols to pyrimidines under atmospheric conditions. Using a well-defined Fe(II)-complex featuring redox noninnocent 2-phenylazo-(1,10-phenanthroline) ligand, as a cat

One-Pot Three-Component Synthesis of 2-Amino Pyrimidines in Aqueous PEG-400 at Ambient Temperature

Jawale, Dhanaji V.,Pratap, Umesh R.,Bhosale, Manisha R.,Mane, Ramrao A.

, p. 1626 - 1630 (2016/09/23)

Amino pyrimidines have been synthesized by a one-pot procedure under environmentally friendly reaction conditions at room temperature. The use of aqueous PEG-400 circumvents the problems associated with the toxic, hazardous organic solvents and oxidizing agents.
